There are countless options for powering gear on the go, but the new RIVER Bank from EcoFlow is looking to take portable power to a new level. A recent article on Mashable gives a solid overview of the new product, which is currently being funded via IndieGoGo.
Claiming to be the largest power supply you can legally take on a plane, the RIVER Bank's stackable system is modular, can be solar powered, and can even jump start your car up to 10 times on a single charge. Its Main Module provides power via two USB-A and two USB-C ports. Adding on the AC Module doubles your power capacity and lets you plug into its 100W AC supply, plus adding third USB-C port. The Car Module adds even more power, plus a jump start port and another USB-C port. When stacked, the modules can charge each other, giving you power where you need it most.
For photographers, this could mean a lot of extra battery charges in the field with a relatively small footprint. Each module weighs between 2.0 and 2.2 lbs, with the full stack coming in at 6.2 lbs. For comparison's sake, a Canon 5D Mark IV with a 70-200mm f/2.8L II comes in at about 5.25 lbs. When you're hiking several miles at a time, every pound counts, but distributing modules between two people makes for a light load and plenty of power for both.
The RIVER Bank will hold a charge for up to six months, so it's always at the ready. Pre-orders are expected to begin delivery in August 2018 for the Main and Car Modules, and in December 2018 for the AC Module.
